+define Package/vwifi/description
+  Simulate Wi-Fi (802.11) between Linux Virtual Machines.
+
+  The vwifi utilities can be used in Hypervisors such as GNS3, QEMU,
+  VirtualBox, VMware, Hyper-V etc. to simulate 802.11 traffic between
+  different virtual machines.
+
+  The utilities use the mac80211_hwsim driver to provide simulated
+  virtual wireless devices to Linux systems and transport the 802.11
+  frames via TCP connections across different machines.
